Summary of ExperienceMy experience is focused on improving
our understanding of the Earth's climate through studies of how aerosols

varied from broad climate response issues to in-depth analyses including:
the radiative effects of cirrus clouds and (nonspherical) scattering by
ice crystals, 3-D radiative transfer in cloudy skies, continuum water vapor

simulations, and the impact of pollution and desert dust on the Earth's
energy balance. This work has been conducted in association with
